Polyoxymethylene is a hard and dense material with a smooth and glossy surface, light yellow or white in color, and semi transparent in the thin-walled part. The combustion characteristics are easy to burn, continuing to burn after leaving the flame. The upper end of the flame is yellow and the lower end is blue, with melting and dripping, and a strong irritating formaldehyde odor and fishy smell. Polyoxymethylene is a white powder, generally opaque, with good coloring properties, a specific gravity of 1.41-1.43 grams per cubic centimeter, a molding shrinkage rate of 1.2-3.0%, a molding temperature of 170-200 ºC, and a drying condition of 80-90 ºC for 2 hours. The long-term heat resistance of POM is not high, but it can reach 160 ºC in the short term. Among them, the short-term heat resistance of homopolymer POM is more than 10 ºC higher than that of copolymer POM, but the long-term heat resistance of copolymer POM is about 10 ºC higher than that of homopolymer POM. Can be used for a long time within the temperature range of -40 ºC to 100 ºC. POM is highly prone to decomposition, with a decomposition temperature of 280 ºC. Stimulating and corrosive gases occur during decomposition. Therefore, mold steel should be made of corrosion-resistant materials.
